When it is time to wake up your roses in spring, nothing does the job like a good shot of nutrients. Roses are heavy feeders and they need a good fertilizer to help them break dormancy and sustain healthy growth throughout the growing season.
Nitrogen, phosphorous, and potassium (NPK) are the major components that most fertilizers offer plants.
In NC, fertilize in early to mid March.
Use 2 cups of fertilizer per rose bush. Dig two small holes on each side of your bush and add 1 cup of fertilizer in each hole. As soon as the fertilizer is put down, the quick release component gives the plant a quick shot of nutrients to get the bush growing. The controlled release fertilizer contines to feed the roses until early fall. With our premium fertilizer, once a year is enough.
We usually suggest 1 cup per bush, but we strongly reccomend you read the package label before proceeding. You will need to fertilize again in May with a slow release fertilizer to feed your rose bush through the end of the growing season.
Rose Tone is a good organic option. Follow label directions for application. You will need to fertilize multiple times through out the growing season with Rose Tone, so it is a good idea to schedule reminders.
There are several methods for eliminating weeds. The recommended method of weed control for your rose garden is to hand-pick any existing weeds and apply a 3-4 inch layer of mulch. We suggest using a hardwood mulch, specifically pine mulch if you can. It is important to use mulch rather than pine straw as pine straw quickly compacts and breaks down adding too much acid to the soil for roses.
Pre-emergent herbicides, those that kill the weed by inhibiting germination of the seeds are less likely to damage a rose bush. These herbicides should be applied in early spring 3-5 weeks before weeds begin to sprout or after you have hand picked the weeds from your garden. A weeding tool, like the garden bandit, can take some of the stress away from hand weeding.
Many weed killers such as Round Up can seriously harm your roses. If used improperly, weed killer can stunt growth, kill the leaves and canes of your rose bush, cause deformation of the plant and inhibit flower formation for the entire season. If you must use a post-emergent herbicide, choose an organic oil based spray that kills weeds by causing the weeds to burn up in the sun.
